VB.NET – End user session

March 29, 2012 - Posted in .NET 4.0, Applications, ASP.NET, JavaScript, VS2010

To end user session and disable user from using a back button to go back to secure page, you need two pages i simply named killsession.aspx and logout.aspx. I will explain both pages with code behind and markup code.

killsession.aspx

killsession.aspx (markup code)


< !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <div>
    </form>
</body>
</html>

killsession.aspx.vb (code behind)


Partial Class Close_Session
  Inherits System.Web.UI.Page
  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) 
                          Handles Me.Load
      Session.Clear()
      Session.Abandon()
      Session.Remove("Name")

      Response.Redirect("logout.aspx")

    End Sub
End Class

logout.aspx

logout.aspx (markup code)

<%@ Page Language="VB" AutoEventWireup="false" 
CodeFile="logout.aspx.vb" Inherits="logout" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

        function doLogout() {
            history.go(+1)
        }
        </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    </div>
    </form>
</body>
</html>


logout.aspx.vb (code behind)

Partial Class logout
  Inherits System.Web.UI.Page
  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) 
                       Handles Me.Load
       'fire-up java code from a markup page
        If (Not ClientScript.IsStartupScriptRegistered("doLogout")) Then
            Page.ClientScript.RegisterStartupScript _
            (Me.GetType(), "history", "doLogout();", True)
        End If
        'redirect user to a page of your choice
         Response.Redirect("default.aspx")  
    End Sub
End Class
